Thanks to having zero astigmatism and negligible spherical aberration and coma, the image produced at zero order at the focal plane of the IsoPlane is of high quality.

The lack of aberrations also means more photons hit fewer pixels, increasing the signal-to-noise ratio of spectra.

“When coupled to a microscope, the IsoPlane can resolve up to 25 line pairs per mm, the Nyquist limit of CCD cameras with 20 micron pixels,” states Ed Gooding, Spectroscopy Product Manager at Princeton Instruments.

Gooding continued, “The IsoPlane can be used from the vacuum UV to the mid-IR, with software-controlled scanning and an interchangeable triple grating turret. It also supports IntelliCal ™, our state-of-the-art wavelength and intensity calibration package. No other spectrometer on the market offers the IsoPlane’s combination of flexibility, resolution, and extraordinary signal-to-noise ratio”.
